Coating machine for drawdown bar experiments

The drawdown bar Coater forms a uniform coating with controllable thickness on the substrate surface by pulling a calibrated metal bar at a constant speed. It is used in laboratories to simulate coating processes, test properties such as leveling and hiding power of coatings, and is suitable for quality control in industries such as inks and paper.
Selection
When selecting, consider the compatibility of the substrate type and size with the film applicator's worktable. Ensure the coating thickness range covers experimental requirements, pay attention to the precision of the coating rod and the wear resistance of its material, evaluate the ease of operation and cleaning maintenance, confirm that the power supply is suitable for the laboratory environment, and ensure operational stability meets the requirements for repeated testing.
